Biochemical sample mixtures are commonly separated in batch processes, such as filtration,
centrifugation, chromatography or electrophoresis. In recent years, however, many research …

Micrometre-scale analytical devices are more attractive than their macroscale counterparts
for various reasons. For example, they use smaller volumes of reagents and are therefore …

The area of micro total analysis systems (μTAS), also called “lab on a chip”, miniaturized or
microfluidic analysis systems, is a rapidly developing field. During the last several years, we …

A panorama of sample preparation methods has been composed from 481 references, with
a highlight of some promising methods fast developed during recent years and a somewhat …

Filtration of molecules by nanometer-sized structures is ubiquitous in our everyday life, but
our understanding of such molecular filtration processes is far less than desired. Until …

Free-flow electrophoresis (FFE) is a technique that performs an electrophoretic separation
on a continuous stream of analyte as it flows through a planar flow channel. The electric field …

Free‐flow electrophoresis (FFE) separation methods have been developed and investigated
for around 50 years and have been applied not only to many types of analytes for various …

The cost, time, and restrictions on creative flexibility associated with current fabrication
methods present significant challenges in the development and application of microfluidic …

Originally developed in the late 1960s, anodic bonding, also known as electrostatic bonding,
field-assisted bonding or Mallory bonding, has become one of the most important silicon …

This paper describes a microfabricated free-flow electrophoresis device with integrated ion
permeable membranes. In order to obtain continuous lanes of separated components an …
